MindPrint DI-PORT
ENGLISH
Dear Recording Specialist,
We are pleased that you picked the MindPrint®DI-PORT as the tool of choice in your quest
for high-quality sound. The DI-PORT is a stereo AD/DA converter designed to satisfy the
most discerning demands.A/D conversion is carried out at resolution of 24 bits, which
assures excellent audio quality that remains intact in further post-processing stages. Next
to its line inputs, the DI-PORT ships with top-notch microphone preamplifiers, so it is well
equipped to deal with both line and microphone signals.The device’s audio output circuit
also features professional-class D/A 24-bit transformers and, with a direct monitoring
option on board, the DI-PORT cures any latency-related ills your computer might have.
The engineers who make up the DI-PORT development team are specialists, highly
experienced hands in tube, audio, mixer and digital technology. These sound "gurus"
invested all of their talents and skills to do justice to the wishes of numerous recording
freaks all over the world. Computer-aided recording has achieved a very high standard over
the last couple of years, while prices have dropped to near universally affordable levels.
Unfortunately, the potential of this equipment is often undermined by the poor audio quality
of soundcards, particularly by sadly inept converters. In combination with your audio card or
a digital I/O card, the DI-PORT puts precisely the qualities that many other converters lack
at your fingertips - all you have to do is exploit them to make the most of your talents and
recording equipment.This is a classic case of technology driving inspiration.
You will be amazed at the difference: Be prepared for a more intense audio experience,
with crystal-clear definition and sparkling, more musical signals that will make your
recordings come alive.
